2006 150 Vmax Carb Starting Problems

[Southfork]

Last couple out of times out my motor does not want to start. Almost acts like its flooded. I run seafoom in it. I have changed the plugs and fuel filter with no improvement.
The bulb is primed and all the battery connections are tight.
Any ideas ?

It's probably the way you're trying to start it. Does it do this all of the time, or just when you FIRST try to start it in the morning?

[Southfork]

Only when i first try and start it. Once its started it runs and starts fine for the rest of the day. This only started happening in the last week or so. I fish two or three times a week so it never sits. It is garaged.
I start it the same way i always have for the last two years. Push the key in hold it for a second and then turn it

[BuzzB8]

Ok, try this:
When you first launch, turn the key to the "on" position and then push in on the key. Don't start it just yet. Can you hear the choke engaging? It should make a tiny clicking noise each time you push in on the choke..."click".

Now, engage the choke and count to three, then turn the key to "start" and release the choke (and key) once it starts. If it sounds like it's going to crap-out, hit the choke again for a second or two. Do this until it's running, it may take doing this two or three times, but should remain running.

Let us know if this works (the choke may need some minor adjusting, and you can do it). Others on here may have a better way (I haven't had a carbed engine for a few years).

Mine does the same exact thing. I think it might be more me than the motor since some more experienced guys start it better than I (reluctantly said). I think I over choke it personally. I'll let you know in April when it freakin thaws out up here...

The boat/motor were new last year

I very much appreciate the help. I went through some of the older threads and saw several about this. Looks like my auto choke is acting up and aint doin the job and i need to pull out the manual choke. Heck i did not even know it had one, but sure enough i looked at the base of the motor and there is it is.
Going out this morning, will post an update

[Southfork]

Primed the bulb this morning, opened the manual choke all the way and turned the key. Fired fist time

[BuzzB8]

Excellent! But did you try what I said? Did you hear the clicking noise?

I've got an 06 150 V-max. Started using the choke on the front of the motor. Fires right off. Saves on the battery.

I got rid of a boat that had an 05 vmax 150 carb becuase it constantly was hard to start.
Prime bulb, then this is critical (as said above):

""When you first launch, turn the key to the "on" position and then push in on the key. Don't start it just yet. Can you hear the choke engaging? It should make a tiny clicking noise each time you push in on the choke..."click".""

Don't try to start until you hear a good click. If that choke doesn't open all the way you will have trouble, will flood engine. Once you are hearing a good click, push key straight in hear click then turn to right to start (don't turn to right as push in this will also cause problems)

The above will solve many problems unless you have a bigger issue.

Good luck

I have the same motor but an 04 and have the exact same problem. Luckily the guy I bought the boat from gave me an on the water demo on how to use the manual choke. I flooded it once or twice but once I got the hang of it it will cold start within 2-3 tries every time, weather I ran it yesterday or 4 months ago. Everyone I talk to tells me the motor is bullet proof so if thats the worst thing that happens, I can deal with it.

My old 150proV (the original V-max carb) has the electric choke on a toggle switch which makes it so easy to use. Even on the coldest days I can get her to fire off and stay running the first time. Of course there was this one time that I pulled off the lower carburetor to clean it and forgot to reconnect the electric choke. I thought for sure that I had screwed up the carbs until I reached back and pulled the manual choke and she started right up.

It seems like that's a pretty common problem with carb'd Yamahas and it's been discussed here a number of time. Here's a link that might help.

If that worked, then..................

Take your cover off, and choke it at the control box with the auto choke, and see if it's engaging the choke on the motor.

[Southfork]

It is working fine on the manual choke.

However i took the cowl off and pushed in the auto choke, sometimes it clicks and sometimes not. When it clicks a couple of times i can turn the key and it starts.

Other times it won't click or takes several seconds to start clicking

Sounds like i will on the manual choke until i get it looked at.

The choke solenoids are notorious for not pulling the linkage enough to fully close the butterflies. If its out of adjustment the smallest amount it won't start without using the manual choke. Been there.
